The Queensland Government is standing by its plan to allow same-sex couples and single parents to use altruistic surrogacy to have a child.

Although both sides of Parliament officially support the decriminalisation of surrogacy, there will be a conscience vote and the Liberal National Party (LNP) will not support the inclusion of same-sex couples and single mothers.

Parliamentary debate is expected to begin later today, but the Opposition has put forward an an alternative Bill that would exclude same-sex and single parents.

Deputy Opposition Leader Lawrence Springborg says the State Government is trying to impose ideas from the "loopy left" on the community.

But Attorney-General Cameron Dick says it is a matter of equality.

"The Queensland Government is firm in its resolve to ensure that all Queensland children are treated equally, that we do not discriminate against children and make some children in Queensland second-class citizens, which is what the LNP seeks to do," he said.

However, the Australian Christian Lobby (ACL) has launched a video and internet campaign against State Government changes to surrogacy laws.

In its video, the ACl says it is not in a child's best interests to be born to a single parent or a homosexual couple.

It says the laws treat children as pets, not humans and it is calling on its members to urgently contact members of Parliament to protest against the passing of the Bill.

Meanwhile, a group which lobbies for the rights of gay and lesbian people in Queensland says it is confident Parliament will pass the bill today.

Louise du Chesne from the group, Action Reform Change Queensland, says outcomes for children of same-sex couples are no different from those with heterosexual parents.

"The only difference that might occur is discrimination and if this Bill fails today, it will be a crying shame for Queensland where that discrimination would be reinforced," she said.

"But I'm actually cautiously optimistic and I'm certainly hoping that our members of Parliament will do us justice and represent the best wishes of the children of Queensland."
